This invention relatesto window sash holding devices and more particularly to an improved form of such holding devices wherein structure is provided to retain the window sash in any of its opened positions without the use of cords or weights, to lock the window sash in any opened, r

or in a closed, position, and to guide the window sash in its opening and closing movements.

One of the objects of this invention is to provide a window sash holding device of such structure that it can be readily applied to new window sash, or installed in sash at present in use.

Another object is to provide in a window sash holdin device means te'guide the window sash during its movements and/or to form a practical weather-strip for the sides of the window frame with which it is used.

A further object of this invention is to provide a window sash holding device which will be relatively inexpensive to manufacture, simple in construction, of pleasing appearanca'compact, and very efiicient and durable in use.

With the above and other objects in view, which will appear as the description proceeds, there has been illustrated in the accompanying drawings a form in which the features and principles of this invention may be conveniently and practically embodied.

In the drawings:

Figure 1 is a front elevation of a window, the sash of which has a holding device embodying the features and principles of this invention operatively associated therewith, a part of the sash and frame being shown cut-away to more clearly show the holding device at one side of the lowe sash of the window;

Figure 2 is a broken front elevational view of the holding device shown in Figure 1;

Figure 3 is a side view of the same;

Figure 4 is a bottom view of the same;

Figure 5 is an enlarged cross-sectional view on the line 5-5 of Figure 2;

Figure 6 is an en arged cross-sectional view on line 6 of Figure 2; and

Figure 7 is a view showing another arrangement of the device of this invention.

Referring to the drawings wherein like reference numerals designate like parts throughout the various views, the reference numeral I I denotes a window frame in which upper and lower window sashes I2 and I3 respectively are adapted to be raised and lowered, The window sashes I2 and I3 are each provided with a groove I4 (see dotted lines in Figure 5) in each of their side edges, which grooves I4 may readily be made in sash at present in use, and in new sash at the time of manufacture.

The sash holding device of this invention is adapted for use with window sash having a groove 5 I4 in its edges and comprises an elongated tubular member I5, the diameter of which is of such size as to permit free movement of the sash thereon while being of sufl'icient snugness to prevent side movement of the sash. The tubular member I5 therefore is adapted to act as a window sash guide during its vertical movements in and'out of closed position. The member I5 is provided with ointed members I6 and H to penetrate the cross-frame member I8 and hold the remote end l5 of the tubular member I5 in place. A strap clamp I9 is provided to encircle the tubular member I5 adjacent its other end to retain this end in place.

The strap clamp I9 is preferably set into the material of the member I5 so that the continuity of the surface of the member I5 will not be interrupted, and is provided with Outstanding ears 2I and 22 which are adapted to rest upon the sides 23 of the window frame I I and be secured thereto by screws 24.

The device also includes as a part thereof a strip of material or slide 25, arcuate in cross-section, which is disposed within the tubular member I5 in a telescoping relation therewith and adapted to slide therein a ainst a portion of the inner periphery thereof. The radius of the arouate shape of the strip of material 25 may be greater than the radius of the interior of the tubular member (see dotted lines in Figure 5) if desired, to obtain greater friction thereon when pressed thereagainst. An end 26 of the strip of material or slide 25 is flattened and bent at right angles to the remainder to form a base adapted to be seated against a cross frame member 2'! of the respective window sash I2 or I3 and be secured 4O thereto by screws 28, whereby the slide 25 will be supported in proper osition relative to the member I5.

A friction imposing shoe 29, generally cylindrical in shape, is provided and disposed within -the member I5 and in ngagement with the inner surface of the arcuate strip or slide 25. The shoe 29 is urged against the strip 25 by a spring 3| which re cts between the shoe 29 and a shoulder 32 provided on a screw stud 33. The screw stud 0 33 has a threaded head 34, adapted to be screwthreaded in the wall of the tubularmember I5, and a shank 35, extending from the head 34, through the spring 3|, and into an opening 36 provided in the shoe 29. Adjustment of the screw 55 head 34 will vary the spring tension of the spring Assuming, for instance, that the lower win' dow sash l3 of the drawing has hadthe deviceof this invention applied thereto in place of the usual weight, cords, and pulleys, the-appearance 15,

will be as shown at the leftin Figure 1, only the tubular member i5 and the strap clamp H s-how ing. The sash l3, may now be raised in t-heusual j manner whereby the arcuate strips'or slides 25, beingattached to the sash l 3,pslide upwardly in the tubular member and are infrictionaliengagementtherewith under the'urge 'of the springs 31.. .Asthe-wind'ow sash 13' is raised it is; guided bythe t'ubular-member I'Sridingin the groove [4" andby. the slide, 25 ridingiin the member ii. A 25 smooth, easy and non-cramping sliding action is thus. mai'ntainedlwhile raising 'or lowering the sash due, to. eitheror both of. these guiding features... Thewindow sash. will remain in any of ,1- its. raised. positions. due to the. counterbalancing 3 action ofthefrictional engagement of the shoe 29 with theslid'e fiend/or the frictionaien gagementoifitheslide 25 with the member i5, the necessary friction being: obtainedlby adjustment of'thescrew stud 33 as above described. When 35 in a...desiredi.raised' position the sash maybe locked-byscrewing in the pointedv set screw 31 to prevent unauthorizedmanipulation oi thewindow sash from. the-Outside. It will be understood thatthe. upper. sash l2 may also havea similar de- 4 vice applied thereto ateach of its,si'deedges, the parts-0t the device being reversedtoprovid'e the advantages thereof'to this sash. ,7 V 1 There is illustrated in.Figure.7 a, reverse. ar- 1 rangem'ent of the parts of the holder of, thisinventiona In this arrangement' the tubular member l'iissecured to the, sash within the groove l4 therein and the arcuate slide 25 is attachedto the ftrame andtelescopeswithin the member l5. The action is the, same as in. the; previously described arrangement but this arrangement has an added advantage. thatthe tubular member I51 being disposed between the frame. andthe sash. wilLtend. to act. as. a Weatherstrip. therebetween. While there has beenshown and described herein onesform in which the features and principlesoflthis inventionmay be' embodied in practice, it is tobe understood thatthe same may 1 be. embodied in other specific forms without departing from the spirit and essential attributes thereof,,and it is therefore, desiredthat. the present. embodiment-be considered in alllrespects. as illust'ratedg'and not. restrictive, reference being had, to. the. claims rather than, to the foregoing description tdindicate the. scope of'.the.inven.- tion.,,-.-.
